It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] See also Figures 1 to 5 The embodiment of the utility model provides a quantitative feeding device for resin mixing and stirring, and the quantitative feeding device for resin mixing and stirring comprises a horizontal feeding barrel 1, a valve core 5, a rotary adjustment component 6 and a collection component 7.

[0024] In the embodiments of the present invention, please refer to Figures 1 to 5 The upper cylinder surface of the horizontal blanking cylinder 1 is fixedly mounted with a feed flange 2 connected with the horizontal blanking cylinder 1, and the front and rear cylinder surfaces of the horizontal blanking cylinder 1 are respectively fixedly embedded with a discharge pipe 3 and a metering cylinder 4, and a rotatably connected valve core 5 is provided in the horizontal blanking cylinder 1, and a three-way material passage opening is provided on the valve core 5, and the three-way material passage opening structure on the valve core 5 is composed of a feed opening 5a, a discharge opening 5b and a return opening 5c, and the feed opening 5a, the discharge opening 5b and the return opening 5c ​​are all opened in the middle of the valve core 5 and arranged radially along the valve core 5, and the feed opening 5a, the discharge opening 5b and the return opening 5c ​​are connected with each other and form a three-way structure;

[0025] The metering cylinder 4 is provided with a rotary adjustment component 6 for driving the valve core 5 to change the direction of the material passage, and the rotary adjustment component 6 includes a hydraulic cylinder A61, and the hydraulic cylinder A61 is rotatably mounted on the metering cylinder 4 through a mounting bracket 62, and a sleeve ring 63 is fixedly mounted on the output end of the hydraulic cylinder A61, and the sleeve ring 63 is sleeved on the rotating rod of the side wall of the connecting plate 64 and is rotatably connected to the rotating rod, and the connecting plate 64 is fixedly connected to the rotating shaft of the horizontal blanking cylinder 1 extending from the valve core 5.

[0026] It should be noted that: the feed flange 2 is fixedly connected to the feeding port of the resin mixing box. When the box mixes the resin and the ingredients, the output end of the hydraulic cylinder A61 is opened to return, so that the valve core 5 rotates until the feed port 5a rotates to communicate with the metering cylinder 4, and the valve body on the front side of the valve core 5 rotates upward and blocks the feed flange 2, thereby achieving the sealing of the feed flange 2 to avoid leakage when the mixing box is stirred;

[0027] After the resin is mixed and stirred in the mixing box, the output end of the hydraulic cylinder A61 is opened to move the valve core 5 back, until the feed port 5a is rotated to communicate with the feed flange 2, the return port 5c is connected with the metering cylinder 4, the discharge port 5b faces the lower part of the inner wall of the horizontal blanking cylinder 1, and the valve body opposite to the return port 5c blocks the discharge pipe 3. At this time, the metering cylinder 4 is driven to form a negative pressure through the collecting assembly 7, and the resin in the mixing box flows into the metering cylinder 4. The flow stroke of the resin material is: feed flange 2→feed port 5a→return port 5c→metering cylinder 4; after completing the quantitative acquisition of materials, open the output end of the hydraulic cylinder A61 to move the valve core 5 to rotate until the feed port 5a is rotated to be connected with the metering cylinder 4, the discharge port 5b is connected with the discharge pipe 3, the return port 5c is facing the lower part of the inner wall of the horizontal blanking cylinder 1, and the valve body opposite to the return port 5c blocks the feed flange 2, and then the resin in the metering cylinder 4 is driven to be discharged through the collecting assembly 7. The flow stroke of the resin material is: metering cylinder 4→feed port 5a→discharge port 5b→discharge pipe 3.

[0028] In the embodiments of the present invention, please refer to Figure 1 and Figure 4 The metering cylinder 4 is equipped with a material collection component 7 for driving the metering cylinder 4 to form a negative pressure to suck back the resin mixture, and the material collection component 7 includes a hydraulic cylinder B71, which is fixedly installed at the bottom of the metering cylinder 4 through a bracket, and the output end of the hydraulic cylinder B71 faces away from the horizontal blanking cylinder 1 and is fixedly installed with a center connecting plate 72, a piston rod 73 is fixedly installed on the center connecting plate 72, and a piston 74 is fixedly installed on the rod head of the piston rod 73. The hydraulic cylinder B71, the center connecting plate 72 and the piston rod 73 form a U-shaped structure, the piston rod 73 is inserted into the metering cylinder 4, and the piston 74 on the rod head of the piston rod 73 is slidably connected with the metering cylinder 4;

[0029] It should be noted that: when it is necessary to obtain a certain amount of resin, after setting the stroke length of the hydraulic cylinder B71, the hydraulic cylinder B71 is turned on to drive the output end of the hydraulic cylinder B71 to move forward, so that the piston 74 on the piston rod 73 slides toward the tail of the metering cylinder 4 driven by the middle connecting plate 72. At this time, a negative pressure is formed in the metering cylinder 4 and drives the resin material to flow into the metering cylinder 4. The negative pressure formed can accelerate the rate of resin discharge from the mixing box. After obtaining a certain amount of resin, the hydraulic cylinder B71 is turned on to return, so as to drive the piston 74 on the piston rod 73 to push the resin in the metering cylinder 4 outward to complete the discharge from the discharge pipe 3. Since the resin in the metering cylinder 4 is discharged externally through the piston 74, the error value of quantitative discharge caused by the resin remaining in the metering cylinder 4 is avoided.

[0030] The metering cylinder 4 is provided with capacity scale lines to control the quantitative amount of the resin.

[0031] The working principle of the quantitative feeding device for resin mixing and stirring provided by the utility model is as follows:

[0032] The feed flange 2 is fixedly connected to the feeding port of the resin mixing box. When the box mixes the resin and the ingredients, the output end of the hydraulic cylinder A61 is opened to return, so that the valve core 5 rotates until the feeding port 5a rotates to communicate with the metering cylinder 4, and the valve body on the front side of the valve core 5 rotates upward and blocks the feed flange 2, thereby achieving sealing of the feed flange 2 to prevent leakage when the mixing box is stirred;

[0033] After the resin is mixed and stirred in the mixing box, the output end of the hydraulic cylinder A61 is opened to move the valve core 5 back, until the feed port 5a is rotated to connect with the feed flange 2, the return port 5c is connected with the metering cylinder 4, the discharge port 5b faces the lower part of the inner wall of the horizontal blanking cylinder 1, and the valve body opposite to the return port 5c blocks the discharge pipe 3. At this time, the metering cylinder 4 is driven to form a negative pressure through the collecting assembly 7. Specifically, after setting the stroke length of the hydraulic cylinder B71, the hydraulic cylinder B71 is opened to drive the output end of the hydraulic cylinder B71 to move forward, so that the piston 74 on the piston rod 73 slides toward the tail of the metering cylinder 4 driven by the middle plate 72. At this time, negative pressure is formed in the metering cylinder 4 and drives the resin material to flow into the metering cylinder 4, and the negative pressure formed can accelerate the resin discharge. The rate of the resin material flow stroke is: feed flange 2→feeding port 5a→returning port 5c→metering cylinder 4; after completing the quantitative acquisition of materials, open the output end of the hydraulic cylinder A61 to move the valve core 5 to rotate until the feed port 5a is rotated to be connected with the metering cylinder 4, the discharge port 5b is connected with the discharge pipe 3, the return port 5c is facing the lower part of the inner wall of the horizontal blanking cylinder 1, and the valve body opposite to the return port 5c blocks the feed flange 2, and then the resin in the metering cylinder 4 is driven to be discharged through the collecting assembly 7. Specifically, the hydraulic cylinder B71 is opened for return stroke, thereby driving the piston 74 on the piston rod 73 to push the resin in the metering cylinder 4 outward to complete the discharge from the discharge pipe 3. The resin material flow stroke is: metering cylinder 4→feeding port 5a→discharge port 5b→discharge pipe 3.
